Can someone please tell me if this looks like sunburn on my vanda. It is a reddish color. We are in Florida and my girls get lots of sun. I have a 50% aluminet shade that is directly over the top of them only. The others do not seem to have much more than a few dark spots here and there, just looks like vanda stuff. This vanda is V.Lumpini Red X V. Thongchai-Pink.
